Choosing a graphics cards may cause severe chest pains... :)

[The Zune Guy]

I'm on the verge of ordering my upgrades at the moment...except I have a query over my GPU choice (Why wouldn't I with the variety that exists!)
I've just found a number of sites suggesting that one doesn't need 1GB of video memory on the HD 4890 at my resolution (VGA Monitor @ 1680 x 1050, I couldn't afford a DVI one at the time )
So, can anyone advise me:
HD 4870 512mb
Newegg.com - POWERCOLOR AX4870 512MD5 Radeon HD 4870 512MB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards
HD 4870 1024mb
Newegg.com - MSI R4870-T2D1G Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards
HD 4890 1024mb
Newegg.com - HIS H489F1GP Radeon HD 4890 1GB 256-bit PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards

I'm looking at the HD 4890 at the moment since its $35 more than the HD 4870 1gb, which isn't much (I can overclock it too) but if the HD 4870 512mb will suffice I'll jump for that (i.e. Doesn't drop too many frame)
Thanks for any help!

For the resolution you play at the 512 would be fine. If you plan on upgrading your monitor any time soon I would go for the 4890.

I thought much the same...I would like the HD 4890 but there's no way I should/could waste that money when i will see no benefit.
So just stick with the HD 4870 512mb ya?
And I only just upgraded my monitor, from 19" to 22". Can't afford to go 24" yet, at least not while I'm living in "Rip-Off Ireland"

512mb should be fine on most current games. Though I think GTA4 and maybe a few others would benefit from the 1GB. And how often do you upgrade? If not often then maybe spend the extra money for the 1GB. Personally I would grab the 1GB one since its only $13 more after rebate. Or get this 1GB for $140-$20mir (though I think yours has the better cooler MSI R4870-T2D1G Radeon HD 4870 1GB GDDR5 PCI Express x16 (2.0v) Video Card Retail at ZipZoomfly

Good point. You're right, I'll just grab the 1gb version. It will suffice!
And I upgrade every year, although I've college this year so I'll probably be broke by next summer!
I'll stick with mine I think, MIR's are a bit hard to organise from Ireland
